새로운 영구자석 배열에 의한 X-Y 평면 모터의 특성해석

In this paper, a synchronous permanent magnet planar motor (SPMPM) with new permanent magnet array is proposed and the magnetic field distribution is obtained analytically by using magnetic scalar potential. Compared to those of Asakawa, Chitayat and experimental data, the superiority and feasibility of the novel magnet array are verified. The characteristics of the synchronous permanent magnet planar motor with this novel magnet array such as inductance, back-EMF, and force are calculated by analytical method.
